If a deployment’s pod template use a “RWO,ROX” PVC, during a rolling update,K8S should start the new version pod first,when the new version pod is available,then shut down the old pod.
However, when the new pod start,it will try to use the same PVC ,which is read wirte once, I wonder if the new pod could start successfully
No, the only way with RWO PVC is use in rolling update recreate strategy: .spec.strategy.type==Recreate. Or use statefulsets, statefulsets rolling updates
